Men can also experience hot flashes like menopausal women-if they undergo chemical castration.New findings have verified a way to detect hot flashes.This could help develop treatments against these uncomfortable events in patients who endure chemical castration for medical reasons.Chemical castration involves hormonal drugs that suppress testosterone and therefore the male sex drive.The procedure is employed as a punishment for male sex offenders in some American states and also performed on prostate cancer patients to help deplete testosterone and thus slow the disease.

Japanese researchers have developed a prototype miniature robot that can be inserted through an incision and used to perform medical procedures deep inside the body. The beetle-shaped robot,which weighs five grammes and measures two centimetres in length and one in diamter, is the result of three years of work by researchers from Ritsumeikan University and its partners. The tiny robot incorporates various medical devices including a small camera, sensors and a drug delivery injector, which could reduce the need for surgery. Data is sent to a computer through a slim cable although researchers hope to develop a transmitter.
